Application filed September 523, 1886. Serial No. 214,331.

To all whom, it may concern.-

Be it known that 1, JUNE A. PIERCE, a citizen of the United States, residing at Olaremont, in the county of Sullivan and State of New Hampshire, have invented certain new and useful Improvements in Automatic Felt vor \Vire Guides for Paper-Making Machines; and I do vhereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to mechanism for automatically guiding and regulating the felt or wire-cloth of paper-making machines, but it is equally as well adapted for use in connection with any traveling belt or apron running over or under a roll or series of rolls, as the apron is the actuating agent by which the guide is brought into use.

Traveling belts and aprons,and particularly the felt or wire-cloth in a paper-machine, always have a tendency to stray laterally from their proper course, and the object of a guide is to check these movements and cause the apron to maintain a straight-forward uniform course. This is generally done by so arranging the guide that when the apron shifts sidewise it acts upon the guide and causes an axial change in the position of the conducting-roll which effects the desired results. I propose to guide the felt or wire-cloth in the same general way, but with a more direct and quicker action of the parts; and to this end the invention consists in the construction and arrangement of the mechanism, all as will be more fully hereinafter described and claimed.

For the better understanding of my invention attention is invited to the accompanying drawings, in which similar letters denote corresponding partsin each figure, and in which Figure 1 is a perspective view of the conducting-r01], the guide, and its co-operative n1echanism; Fig. 2, an end elevation of the same; Fig. 3, a plan view; Fig. 4, a side elevation,partly in section; and Fig. 5, a vertical section of the sliding or reciprocating bearing for the conducting-roll.

A denotes the conducting-roll, over which the felt or wire-cloth A passes to the return- (No model.)

roll A. This conducting-roll is supported at one end in a fixed standard, A, bolted to the bed-plate O, and at the other end is supported in a sliding or reciprocating bearing, B, arranged upon a standard, B, bolted to the bed plate 0. This standard B is arranged at a right angle to the axis of the conducting-roll and has two longitudinal side flanges, b b, which guide the bearing B in its movement back and forth upon said standard. This bearing is guided above by a cap-plate, B, which is about as long as the standard B, and is secured thereto by bolts 1) b, which pass through respective tubes 12 b at each end. These tubes hold the cap-plate above the standard far enough to allow free movement of the sliding bearing between said cap-plate B and standard B.

The sliding bearing B is preferably a casting consisting of a square block, a, and an adjoining extension, a. (Fully shown in the detail, Fig. 5.) Part a is that portion which moves upon the standard B and has a central opening to receive the shaft 0 of the conducting-roll A. The shaft 0 at this end carries a spiraldriving-gear, G which plays within a socket, c, of the extension at of the sliding bearing B, and meshes above with another spiral gear, D, arranged at a right angle thereto between two ears, (I d, of the extension a of the sliding bearing B. This gear D has tubular hub-bearings in said ears d d and is adapted to work back and forth with the sliding bearing B by being splined to a feed-shaft, D, which passes E is a right or left hand screw-shaft arranged parallel with the feed-shaft D below and passing through a properly screw-threaded ear, 6, of the extension a of the sliding bearing B, and also through a bushing, e, in that portion of the standard B which supports one end of the feed-shaft D.

The bushing e is secured by a set-screw, c and on the end of this screw-shaft E, outside of and nextto its bearing in the extension of standard B, is splined a toothed wheel, F, by which the said shaft E is operated to move the sliding bearing B to shift one end of the con- I roll.

screw-shaft E, and next to the hub of the toothed wheel F, is fitted a flanged bushing, f, "which clamps the toothed wheel by means of anut, f, screwed on this end of the screw-shaft E. On this bushing f is loosely mounted a rocker-shield, G, the upper end of which is curved and flanged so as to cover about onefourth the circumference of the toothed wheel F, for a purpose hereinafter understood.

On the end of the feed-shaft D, outside of and next to its bearing in the standard B, is secured a disk, 9, having near its periphery on the outside a pin or stud, 9'', upon which are hung two oppositely-disposed pawls, H H. These pawls, which are held in place by a nut, g, are united by a spiral spring, h, and are so arranged as to ordinarily rest upon the flange of the rocker-shield G out of engagement with the toothed wheel F. This is the position of the pawls when the felt or wire-cloth is pursuing its proper course over the conducting- To give effective action to either of the pawlsthat is, to bring them into engagement with the toothed wheel F, so as to rotate the screw-shaft E, and in turn move the sliding bearing B to shift one end of the conductingroll-it is necessary to tilt or depress that end of the rocker-shield upon which rests the pawl to be used. Either of these movements is effected by tilting the shield, which is actuated by a lever, I, which is made fast at its center to a rock-shaft, J, presently to be described. The lower arm, is, of this lever extends down to the rockershield G, and is connected thereto by a pin or stud, Z, which works in a slot, Z, in the lower end of said arm. The upper arm, k, of this lever is formed into a segment and supports one end of the shipper-rod K, which carries the two adjustable guide-plates L L and which ex tends transversely across the traveling felt or wire-cloth. The opposite end of this shipper-rod is likewise supported upon a similar-shaped standard, M, having lower pivot-bearin gs between two ears, m m, of a bracket, N, bolted to the bed-plate 0. Over each end of the shipper-rod is clamped an arm, 0, by means of a setscrew, n, and these arms are held in connection with the lever I and standard M by a pin, 0, on the top of each. The guide-plates L L are likewise clamped to the shipper-rod by means of set-screws n. The rock-shaft J, to which the lever I is secured, is arranged parallel with the feed-shaft D, and back of the same in substantially the same horizontal plane, and is journaled at each end in bearings 19 p, secured to the cap-plate B of the standard B. This rock-shaft has two projecting ears, 1' r, the former being above and the latter being below its horizontal center. The object of these ears and their arrangement is that when the sliding bearing B is moved forward or backward thelug s on its extension a will engage with the ears r and r and tilt the shaft J either up or d0Wn,-as the case may be. For instance, supposing the sliding bearing B to be moving toward the end bearings of the several shafts, then in-passing the ear 1" its lug s would make contact with said ear from below and tilt the shaft J u pward,and, on the contrary, if moving in the opposite direction, the lug 8 would make contact with ear 0 from above and tilt the shaft J downward, and hence both the lever I and the rockershield G would be tilted, so that one of the pawls H would be disengaged from the toothed wheel F,while the other one would be made to engage therewith, thus either time reversing the screw-shaft and the sliding bearing.

As the conducting-roll revolves motion is imparted to the feed-shaft and to the pawls which are hu ng thereon, and, if the felt or wire cloth is moving forward and uniformly, with its side edges instraight lines of direction, the said pawls will work eccentrically without engaging with the teeth of the wheel F; but as soon as it begins to shift sidewise it will crowd itself against one of the guide-plates L, which will shift the shipper-rod K, and in turn tilt the lever I and the rocker-shield G. By tilting this shield one of the pawls II will be thrown into engagement with the toothed wheel F, which will actuate the intermediate connections so as to shift the one end of the conducting-roll. By thus changing the axial position of the conducting-roll it tends to give the felt or wire-cloth lateral divergence in an opposite direction, whereby it may be shifted Having thus described my invention, what I claim, and desire to secure by Letters Patent,
